Abstract

PCT No. PCT/DE95/00595 Sec. 371 Date Jun. 10, 1996 Sec. 102(e) Date Jun. 10, 1996 PCT Filed May 3, 1995 PCT Pub. No. WO95/31430 PCT Pub. Date Nov. 23, 1995The invention relates to a process for recovering amines from acid amine salt solutions by the addition of bases and evaporating the solution at a pH of 11 to 13 in a kneading drier until a useful solid is obtained as the distillation residue and a device for separating sludges and suspensions into a solid and a plurality of liquid fractions separated according to their boiling point. The low-water-content amine phase separated out by distillation is dehydrated with calcium oxide or potassium hydroxide and then separated into pure amine fractions by rectification. The process described makes it possible to utilise all the secondary flows and completely recycle the amines and the absorption medium (sulphuric acid). The flows for the recycling process are amine-charged washing acids from absorbers obtained from the cleaning of amine-containing exhaust gases, produced for instance in the cold box process for hardening core sand in foundries.
